Vehicle i.e. hybrid vehicle, operating method, involves determining drive torque based on sum of another drive torque and variation value, such that vehicle is driven with former drive torque
The method involves determining a drive torque necessary for maintaining an engine idle speed of an internal combustion engine (31) and an electric motor (34) by a regulator (45) i.e. proportional-integral-derivative controller. An angle variation is detected between undergrounds and horizontals by detecting signal of an acceleration sensor (37) to accelerate a vehicle in a longitudinal direction. A variation value of the torque is determined from the angle variation. Another torque is determined based on a sum of the former torque and the value. The vehicle is driven with the latter torque. Independent claims are also included for the following: (1) a computer program product with instructions for controlling a method of operating a vehicle (2) a controller for a drive motor of a vehicle, including a regulator.
